When Shawn and Shane Tiffany took over the former Black Diamond feed yard in 2007 it wasn’t in terrible shape, mostly because of manure applications that kept organic matter in the soil. But after going to a cover crop field day 8 years ago, the brothers didn’t want to just settle.

While it’s not a new concept, an increasingly popular practice is to plant cash crops directly into living cover crops. The science behind it is sound – allowing producers to push the benefits of their cover crops to the max and take advantage of things like added organic matter and nutrient release.

By definition, anything that was or is alive is considered organic matter because it contains carbon-based compounds. This article covers some of the considerations around using organic soil amendments. The most common types of soil organic amendments are manure, compost, and crop residue (including cover crops).

Adam Kramer, a certified crop advisor from Patch Grove, Wis., describes how he helped increase organic matter using cover crops by 0.4% in just 3 years and why he recommends aerial seeding covers. Kramer was a speaker at the Wisconsin Cover Crop Conference in Stevens Point, Wis.

Recent research published in the Soil Science Society of America Journal compared farming systems that received different amounts and types of organic matter sourced from compost and cover crops. The results reiterated that soil enzyme activity confirms the importance of frequent cover cropping in tillage-intensive organic vegetable production.
